The Space Trilogy. An amazing trilogy that I absolutely loved reading. It was utterly unlike anything I expected, yet still managed to far surpass any expectation and pre-conceived notion about the text.
Each book in the trilogy can be read separately, or in the larger unit, which is what I did.
That Hideous Strength was interesting. The Medieval feel to it was nice (I like Arthur and the Round Table and such) and I thought Lewis did a good job of bringing tension to the table and keep your emotions tied up. In a good way, of course, it made you want to keep reading - not stop reading. It also references Numinor. If you aren't familiar with Numinor, read the works of J.R.R. Tolkien. I thought that was nifty, it gave Middle-earth and the Trilogy a more "real" feel because there was a cross-reference. All in all, though, this is definitely my least favorite in the trilogy. I think Lewis tried to pack a little much into the book (it's twice as thick as the others, and a much slower read.)
Really all of the books were wonderful and I highly recommend them. Middle school-aged and above should be able to appreciate the Space Trilogy. If you can only read one of them, for some reason, I would suggest Perelandra, mainly because of the depth of thought in that book. I would recommend Out of the Silent Planet if you want to reawaken a sense of wonder, and I would submit That Hideous Strength to you if you were interested in modern development and a modern good vs evil in a somewhat more applicable way as it deals post-fall instead of pre-fall as in Perelandra.
C.S. Lewis is just an amazing writer. I have never read something of his I did not enjoy. Not that I've read everything he wrote, but I have read a decent portion of it. If you ever want to be challenged and read something understandable and well written, pick up C.S. Lewis.
